Abstract

The invention discloses a large-scale civil aircraft power supply and distribution system ground test integrated verification test platform architecture, builds a large-scale distributed measurement and control system based on Ethernet, and realizes network data exchange based on multi-machine synchronous data acquisition technology and Client-Server technology , to realize nanosecond-level synchronization of system time under the distributed network structure, and to ensure the homology and synchronization of the distribution control logic communication data and measurement data. A digital simulator based on the aircraft flight profile function solves the problem of decoupling between the aircraft electrical system and avionics and other systems in its ground test, and realizes the cross-linking measurement and control of the aircraft electrical system and other systems such as avionics and power systems. Operation program man-machine interface verification function. The proposed integrated verification test platform architecture can provide reliable experimental basis and means for design optimization and fault location of large civil aircraft electrical systems.

Description

technical field [0001] The invention mainly belongs to the technical field of aircraft power supply system experiments, and in particular relates to an integrated verification test platform architecture for ground tests of power supply and distribution systems of large civil aircraft. Background technique [0002] In recent years, with the introduction of multi-electric and all-electric aircraft, distributed power distribution technology has been widely used in independent power systems such as multi-electric and all-electric aircraft in the future. Traditional secondary energy systems such as hydraulic, pneumatic, and environmental control Replaced by electric energy, the role of the power system in the aircraft is becoming more and more important. Therefore, in order to meet the requirements for the design verification and airworthiness test of the aircraft electrical system, it is necessary to design a number of integrated test systems that meet the design specifications a...
